Engineering firm Worley has won a contract from gas major Santos for professional services to support the Bayu-Undan carbon capture and storage project offshore northern Australia in the Timor Sea.

Santos first announced it would convert the Bayu-Undan field reservoirs into a CCS project in March this year.

The field will cease commercial production mid-next year and has capacity to store 10 million tonnes of CO2 per year. The project will take CO2 from the nearby Barossa project and potentially other fields. Barossa has a relatively high CO2 content at about 20%.

Santos has already committed to storing CO2 from other third parties including JERA, INPEX and Tokyo Gas.

Worley announced it had been awarded front-end engineering and design work for the project.

This includes the re-purposing of the Bayu-Undan facility and the offshore section of the gas export pipeline which will be converted into a CO2 injection pipeline.

Worley chief Chris Ashton said he was excited to strengthen the firm's relationship with Santos.

"This project is one of the ways we are helping our customers to decarbonise and re-purpose existing assets as we deliver a more sustainable world," Ashton said.

The FEED work will be executed from Worley's Perth office with support from global teams.
